The Defining Series: Drilling Fluid Basics | Schlumberger

Drilling ,fluid, design and maintenance are iterative processes affected by surface and downhole conditions. These conditions change as the well is drilled through deeper formations and encounters gradual increases in tem-perature and pressure and the mud undergoes alterations in chemistry brought about by different types of rock and formation fluids (above).

This is especially true for ,flowback, fluids, which contain high polymer loading. The viscosity and rheological properties ,of fracturing fluid,, significantly affect leak-off rate, proppant placement, length and width of fractures, fracture conductivity, and consequently, the success of the treatment.

Comparatively speaking, hardness is not very high in flowback and formation waters across most of the basins except where ultra-high brines are present. As noted for the Permian, much of this variation is of course due to the geology of the area, but even proximate formations can exhibit striking differences in …

Hydraulic ,fracturing, for natural gas extn. from shale produces waste brine known as ,flowback, that is impounded at the surface prior to reuse and/or disposal. During impoundment, microbial activity can alter the fate of metals including radionuclides, give rise to odorous compds., and result in biocorrosion that complicates water and waste management and increases prodn. costs.

This is called flowback water. The amount of flowback varies, and it can be as little as 10% or essentially most of the water. Typically, 20 - 40% of the water returns to the surface. Initially, this water will primarily contain, contaminants, found in the fracturing fluid.

The fracturing fluids comprised of organometallic-crosslinked derivatized polysaccharide. In one typical example, the viscosity stayed above 100 cP (at 100/s shear rate) for over 80 minutes at 275 °F recorded for a fracturing fluid prepared with untreated produced water with TDS of about 300,000 mg/L and hardness of about 50,000 mg/L.

The fraction of hydraulic ,fracturing fluid, recovered varies from play to play (Table 2). For example, ,flowback fluid, recovered from wells is reported to range from 9% to 35% of the fracture ,fluid, used in the horizontal Marcellus wells in the northern tier of Pennsylvania (Wood et al.) Yoxtheimer (2010) reported an average recovery of ,flowback, of 10% (over 30 days) per Marcellus well.
